date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2). 8 of the 27 named sources that could be read published a usable figure; 19 published none and are recorded as not published, never filled in; 2 could not be read (blocked, dead or unreachable) and count nowhere. The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in % (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 22 figures, never sentences; 355 candidate sentence(s) were refused by a reviewer with the reason recorded. The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): the lowest, median and highest advertised initial rate across every lender publishing a buy-to-let product page, per LTV band, per fix length and per product fee, beside the Bank of England Bank Rate; the spread over Bank Rate, the fee-adjusted true cost, and the movement since the last read - the calculators the keywords ask for are generated from this table rather than from a typed-in default", "embed": "
